17mm Finnisher Serrated Magnetic Wheel Nut Blue (JCO28901)

Blue 17mm Finnisher Serrated Magnetic Wheel Nut is a lightweight, CNC‑machined wheel nut designed for 17mm RC wheels. It features a large flange for extra support, a serrated edge to lock the wheel in place, a closed-end cap to protect the axle from dirt, and built‑in set screws that enable magnetic attraction with a compatible wrench for quick, tool‑assisted wheel changes.

Built to trim weight without sacrificing strength, the nut reduces bulk while preserving a robust clamp to keep wheels seated under load. The blue anodized finish adds durability and a distinctive look. For best results, install from inside the nut and apply a small amount of CA glue to the set screw so it touches the magnet inside the wrench, then allow the glue to cure before use.
